No. Because I promise you you will not like what you see. I know only because I have several people including myself that record fights and watch them on discord. After watching several of them I've gone mad. lol

This was asked in a q & a session back in april. Here is what was said at the time & source link.

Animefangod1: I was wondering if it was possible and if you guys ever would add a feature where you could watch your battles with other players so you could see where you are having trouble in things like arena and TW?
[CVG] We had battle replays and consequently being able to watch other allies battle in the scope for Territory Wars, but unfortunately they had to come out of our update in order for us to get it done in time. There is significant tech work required for synchronous gameplay events which we just don't have at the moment but would really love to do in the future.https://forums.galaxy-of-heroes.starwars.ea.com/discussion/comment/1514793#Comment_1514793

Sparrow: You mentioned battle replays are still a ways off, as a stop gap would it be possible/easier to let us see the team that attacked us in TW and its end state?
[CVG] Would love to, but some of the tech required to preserve the history of the team that attacked you is needed as well. When we realized we couldn't get the battle replays in, we didn't want to ask the engineers to do the underlying tech first.https://forums.galaxy-of-heroes.starwars.ea.com/discussion/comment/1514794#Comment_1514794
